LG dishwashers with model numbers beginning with "LDF" indicate that it has...

 

L---> LG

 

D--> Dishwasher

 

F--> Fully Integrated Controls (at the top of the door)

 

In this service call the customer contacted us to check her dishwasher because she was not able to get it to start a cycle.

 

CUSTOMER COMPLAINT

 

 "The dishwasher was working fine until recently. Now---all it I can get it to do is to power up but the cycle selector (left side) does not allow me to select anything."

"The lights on the right side (cycle modifiers) do come on---but they're also not responding to input as well."

 

CAUSE:

 

At some point in time---coffee had been spilled on the countertop---and ran over the edge onto the top/left of the dishwasher controls.

The customer had wiped up the "mess" and thought nothing of it thereafter.

Once the residual liquid has dried---the sugar that was in the coffee---had created a sticky set of buttons---for the cycle selections.

Once a button/key was selected---it remained depressed and would not return back to it's normal position.

The symptom would be that once the POWER button had be pushed---the right side controls illuminated but the left side did not.

It would then *appear* that the Cycle Selector Board had failed.

 

SOLUTION

 

Remove the front door panel

 

Remove the Cycle Selector Board

 

Peel/remove the rubber (water jacket) padding from the key/buttons

 

Remove all buttons and thoroughly clean (sticky black coffee stains)

 

Re-assemble and test.

Good tip, John!  

 

How about just replacing the touchpanel?  Would that be a more reliable repair or not?

This type of control panel is more like the Bosch dishwasher---with square-shaped buttons.

 

Very different than say---a Frigidaire dishwasher front-control panel (or a Whirlpool/Kenmore)---which has an integrated circuit within the touchpad.

 

The buttons on the LG dishwasher can be disassembled/removed from the control panel very easily and cleaned/re-used (if need be).
